Description

In the manufacture of l-'ilamenigarnen - the expression is also used here for yarns made from staple fibers - it is often necessary to put two yarns together to join, either because the yarn has broken or because the end of the yarn is on a bobbin must be connected to the beginning of the yarn on another bobbin. Although the two ends of the yarn can of course be connected by simple knotting, this approach is undesirable because of the way The resulting knot often gets stuck during further processing and causes further thread breakage. aside from that the knot affects the appearance of the goods made from the yarn.

To overcome these difficulties, there is a method of splicing unstretched or partially stretched Filamenigarnc known in which the two ends the filamentary thread is forward and on two at a distance arranged points are held so that they run parallel and overlap each other and in which the ends are joined together in a vortex zone by fluid entanglement (GB-PS 12 51 514). It follows that the interweaving of Filament yarn in a fluid stream with non-reversible ones or fully drawn filament yarn may be satisfactory, but that with drawable Filament yarns only inadequate, weak splice cords can be produced which do not reliably withstand the subsequent stretching step. According to the prior art, attempts are made to thereby reduce the splice points in the case of stretchable filament yarns to improve that the two ends are exposed to the fluid entanglement only after they have been removed from Hand vorversirecki have been. The degree of pre-stretching corresponds essentially to the possible displacement with the filament yarn in question Aim to be practical after making the splice no further coating of the yarn ends possible IN THE.

Although the pre-drawing of the ends of undrawn or partially drawn yarns for the durability of the Splice point offers certain advantages over the method that works without pre-stretching, is shown in

In practice, the splice point nevertheless yields during the subsequent drawing of the filament yarns unit loosens. In addition, there are also thickenings here present at the splice, which can lead to machine malfunctions when the yarn is subsequently processed

to cause and affect the appearance of the finished product.

The invention is based on the object of the method to improve according to GB-PS 12 51 514 so that it is both very durable and practically thickening-free Establishes connection points.

This object is achieved in that the two fixed ends of the undrawn or partially stretched Yarns are drawn in a predetermined ratio of 2: 1 to 6: 1 that the drawn Ends relaxed between their retaining parts for shrinking and in the relaxed state exposed to a fluid jet for 0.5-10 seconds, which twists them together, so that the spliced yarn is released and that the successive ones Steps with respect to each other step are terminated one after the other in time (claim 1).

This procedure has the consequence that after the fluid interlacing, the connection point is very strong and reliably holds together during the subsequent drawing of the filament yarns. In addition, the connection points produced in this way are only slightly thickened, so that they do not interfere with further processing and are invisible in the finished product.
Another object of the invention is also a

J5 nc Device for splicing undrawn or partially drawn Filament yarns which the method automatically carries out (claim 2 and claim 8). It will for this only protection in connection with the method according to claim 1 is sought.

Although devices for the approximately automatic connection of yarn ends by air entanglement have been proposed (for example US-PS 33 45 809 and 34 77 217), is not suitable, fully automatic and permanently the ends of undrawn or partially drawn ones Joining filament yarns together in uniform joints that are sufficiently strong are to withstand subsequent stretching to an economically feasible level. this is also valid for a well-known device (G U-PS 12 51 514). existing from two spaced yarn clamps, which the two ends of the filament yarns hold parallel to each other, mutually overlapping and out of a chamber in which the fluid interlacing of the Yarn ends takes place.

i-> This device is open at both ends Chamber formed with a circular cross-section in an elongated block and it is for the insertion of the both thread ends accessible by hand through a longitudinal slot in the block. At each open end of the bo chamber is a twine clamp designed as a two-legged clamp into which the twine ends of Hand clamped in such a way that each clamp has the inlet-side part of one end of the thread and the outlet-side part The end of the other end of the twine. A bore opens into the chamber tangentially the outer end of a nozzle of a pistol-shaped actuating device is connected. the one hand-controlled Supply of pressurized fluid into the chamber

possible. The handling of this device is cumbersome and the quality of the splice depends significantly on the manual dexterity of the operator. Also - as in the context of the procedure explained - this device for connecting stretchable filament yarns not suitable because the Splice points are too weak to withstand the subsequent stretching.

The device according to the invention connects the ends of the yarn so firmly that the splice point does not curl during subsequent stretching and is also practically free of thickening. The establishment can be designed as a hand-held device or as a stationary system.

In a preferred embodiment described below, they are used to regulate the work sequence multiply: valves operated one after the other, which after opening Let compressed air into the respective devices. However, there are also other actuating means such. B. Control cam (shown in the alternative embodiment) or limit switches can be used for this purpose.

The arm 84 consists of a first Segment 88, which connects to the rod 80 coaxially to this, a second segment 90, which the segment 88 r <> risei / i and from this imler an angle of runs approximately JO 'towards the horizontal nuchobcn, a third segment 92 which extends horizontally from segment 90 and through a fourth segment 94 which is directed upwardly and rearwardly from segment 92 at an angle of 30 " Rod 82, which is covered in the drawing by rod 80 and housing 10, is of identical design. The rod 80 is freely rotatable in sockets 96, 98 and the rod 82 is supported accordingly. A torsion spring 100 connects the rod 80 to the housing 10 so that it does not move out of its starting position according to FIG. 4th can turn out. Between the rods 80 and 82, an actuating rod 102 protrudes downward, with the Rods 80 and 82 is in operative connection via a pull rope 104, the ends of which around rods 80 and 82 are wound around and its central part is guided around a pin 106 on the actuating rod 102 at the bottom is. On the lower linden of the actuating rod 102 an adjustable bolt 108 is attached, which the Controls the time in which the stretching-shrinking device is actuated during the working sequence.

Changes in the length and angular position of the rod segments change the stretching ratio.

Actuator

The clamping device, the air interlacing device and the shrinking and shrinking devices are operated one after the other by a device which has a trigger 110 which passes through an opening 112 of the housing 10 protrudes downward. At the upper end of the trigger 110 is a pivot arm 114 is formed, which is pivotably mounted on a pin 116 at the end remote from the puller lever is. A return spring 117 within the housing 10 pushes the trigger 110 into the open position.

In the G handle part of the housing 10 are three two-way valves 118, 120 and 122 housed in communication with the main air chamber 124, which is supplied with compressed air through an air hose 126 from a suitable air source. The valves 118, 120 and 122 are opened by pistons 128, 130 and 132, which have contact heads 134, 136 at their lower ends and 138, which are slidable in cylinders i40, 142 and 144. The contact heads 134, 136 and 138 facing away ends of the pistons 128, 130 and 132 are by means of fitting pins 148, 150 and 152 on an im essential horizontal pivot ledge 146 articulated. The pivot ledge 146 is around one in the Housing 10 inserted dowel 154 articulated. The opposite end of the slewing ledge 146 is attached to an upwardly directed pawl 156 with a dowel 158

To hold valves 118, 120 and 122 open for a predetermined period of time for control purposes the desired degree of interweaving of the threads of the yarn sections is part of the device as a regulating mechanism provided that the closing of the valves regardless of the movement of the trigger 110 in controls the open or home position.

This regulating mechanism consists of a control piston 160 which is composed of a main part 162 and a spring 164 / usam ^r ) which is movable in a cylinder 166. A fluid container 168, held under pressure by a spring 170, stands for a fluid via an oil inlet line 172 and an outlet IciUing 174 in the housing 10. I -ulI, associated with the / ylinde ·· IMi. Check valve 176 prevents the return of fluid through line 172 while the rate of return of fluid through outlet line 174 is controlled by an adjustable needle valve 180 inserted therein.

The piston 160 stands with the valve piston 128, 130 and 132 in operative connection via an arm 182, the

i ^r ) protrudes outward from the body 162 and, by means of a pin 186, to a knee lifter directed away from it! 184 is connected. A slot 192 is formed in a connecting member 188, in which a pin 194 can be displaced and which is fastened to the end of the pawl 156 facing away from the pivot bar 146. The pawl 156 has a shoulder 196 between the pins 158 and 194, which, in order to connect the pawl to the trigger lever 110, engages in a disengageable manner with a pin 198 which projects outward from the pivot arm 114.

An actuating pawl 200 is also used to trigger the trigger UO by the control mechanism a toggle joint surface 202 and a release shoulder 204. The actuating pawl 200 is by means of a Dowel pin 206 movably mounted on the pivot arm. The toggle pad 202 is held by a spring 208 pulled against the toggle lever 184. An adjustable screw 210 is inserted into the housing 10, against which the Schuller 204 of the actuating pawl 200 at Downward movement of the pivot arm 114 comes to rest. The toggle lever 184 is an extendable Return spring 212 between the upper end of the toggle lever 184 and the housing 10 against the control piston 160 pressed.

Operation of the Preferred Embodiment

Upon actuation of the preferred embodiment of the hand-held device, the two yarn ends to be connected are held in abutment parallel to one another by the operator who loops them over the arms 84, 86 and through the channels 32 and 34. The trigger 110 is then pulled against the handle of the housing 10 for the sequential operations of the devices described to commence. By pulling off the trigger, the piston 128 is pressed downwards to open the valve 118, so that compressed air can penetrate through the line 119 into the clamping air chamber 18. As a result, the clamping pistons 36 and 38 are moved outwardly against the yarn guides 28 and 30 in order to clamp the yarn ends between the elastic outer disks 24, 26 and the yarn guides 28 and 30, respectively.
After the yarn ends have been clamped, a further movement of the trigger lever 110 causes a downward movement of the actuating rod 102 by pushing the bolt 108 against the trigger lever 110, as a result of which the extension arms 84, 86 move outward into the position shown in FIG. 6 for stretching the yarn sections and then down into the position according to FIG. 7 results in the shrinking (relaxation) of the drawn yarn sections. When the stretching arms 84 and 86 move to the position shown in FIG. 5 ingestion

men, the yarn section is stretched between the two Klcmnipunkten to a predetermined extent, z. B. from 2: 1 to 6: 1, typically from 3: 1 to 5: 1, depending on the angular positions of the segments of the arms 84 and 86 and the yarn portion is then further movement of the Verstreckungsarme 84, 86 in the position according to Figure 6 relaxed. The movement of the stretching arms 84 and 86 from the position of FIG. 6 in the position according to FIG. 7 guides the two yarn sections downward into the channel 48 of the block 46.

Then the valve 120 is opened by moving the piston 130 , so that compressed air can flow from the chamber 124 through the line 121 to the cover chamber 74, so that the piston 70 in the chamber 74 rises and the lever arm 66 around the dowel 68 to lower of the cover 64 swivels against the block 46, among other things, the Luftverfieehtungsvorrichtung is ready for operation.

Finally, piston 132 is contacted by valve 122 to allow air from chamber 124 to flow through conduit 123 to chute 48 through nozzles 56 and 58 creating turbulence in chute 48 which intertwines the filaments of the two yarn sections cause.

Pulling the trigger 110 against the housing 10 causes the control piston 160 to be withdrawn from the cylinder 166, whereby fluid penetrates through the inlet line 172 into the cylinder 166 as a result of the vacuum created and the pressure of the spring 170.

When the trigger 110 is fully pushed back, the shoulder 204 of the actuating pawl 200 contacts the screw 210 and the connecting surface 202 separates from the toggle lever 184 so that the toggle lever 184 can pivot about the pin 116 under the action of the return spring 212. The piston 160 then moves under the action of the spring 212 into the cylinder 166 and pushes fluid back into the container 168 through the outlet line 174 , with the return rate of the piston 160 over a predetermined period of time, e.g. B. 0.5 to 10 seconds, preferably about 1.5 seconds, is controlled by a needle valve 180 , so that a sufficient interweaving of the yarn threads and uniform connection points are guaranteed from operation to operation.

The return of the toggle lever 184 also pulls the shoulder 196 of the pawl 156 away from the pin 198 , so that the trigger lever 110 is released and can automatically return to its starting position under the action of its return spring 117. The upward movement of the pawl 156 under the action of the toggle lever 184 closes the valves lie, 12 and 122 one after the other to complete the process. When the process is complete, the connected yarn ends are removed and excess yarn is expelled.
